AI Technical Summary

Benefits of technology

The method effectively compensates for light leakage, ensuring that displayed colors correspond to the intended values, thereby improving image quality and user experience by minimizing color tinting and ghosting artifacts.

Problems solved by technology

Color filters implemented on LCD screens or panels often operate in an imperfect manner.
Light leakage may manifest in various ways to users and may result in undesired user experiences.
For example, light leakage may result in color tinting, where images presented on a display include colors that differ from those expected based on pixel color values provided to the display.
In some instances, light leakage causes image ghosting artifacts, especially for devices or instances in which one or more optical elements intervene between display panels / screens and an observer (e.g., a user's eye or another image detector / sensor).

Example Method(s) for Light Leak Correction

[0083]The following discussion now refers to a number of methods and method acts that may be performed. Although the method acts may be discussed in a certain order or illustrated in a flow chart as occurring in a particular order, no particular ordering is required unless specifically stated, or required because an act is dependent on another act being completed prior to the act being performed.

[0084]FIGS. 5, 6, and 7 illustrate example flow diagrams 500, 600, and 700, respectively, which depict acts associated with facilitating light leak correction for one or more display devices. The discussion of the various acts represented in the flow diagrams include references to various hardware components described in more detail with reference to FIG. 1.

[0085]Act 502 of flow diagram 500 includes obtaining a color value for a pixel. Act 502 is performed, in some instances, by a system 100 utilizing processor(s) 102, sensor(s) 110, I / O system(s) 1...

Abstract

Systems are configured for facilitating light leak correction for a display device. The systems are configured to obtain a color value for a pixel and obtain a light leak value associated with the pixel. The light leak value is based on a measured light leakage associated with a color filter of a display device configured to display the pixel. Systems are also configured to generate an updated color value for the pixel by applying a light leak compensation operation to the color value for the pixel. The light leak compensation operation uses the light leak value as an input for modifying the color value to compensate for light leakage that may otherwise occur when displaying the pixel on the display device. Systems are also configured to trigger display of the pixel on the display device using the updated color value.

Description

BACKGROUND[0001]Many display systems include display panels that comprise a collection of pixels for displaying image content to users. Some display systems, such as liquid crystal displays (LCDs), utilize one or more back lighting elements that emit white light in conjunction with color filters to display a colored image. For example, different pixels of an LCD may each comprise a respective set of color filters, with each color filter being associated with a different color channel (e.g., a red channel, green channel, or blue channel, according to the RGB color model). In this way, each pixel may be configured to display different color values (e.g., different brightness levels of red light, green light, or blue light, according to the RGB color model).[0002]Color filters implemented on LCD screens or panels often operate in an imperfect manner. For example, a color filter of a pixel configured to transmit green light (e.g., for a green color channel) may fail to filter out all re...
